replica-skill

Replica is eleven Claude skills that walk an agent through rebuilding someone else's app: map its screens and flows, plan the stack, build, test, score against the original, rename and ship. The standout is the Entrepreneur skill, which ranks what users complain about in real reviews so your version fixes it. MIT, no signup, no API key.

Install is copying eleven folders into ~/.claude/skills/. The six helper scripts are standard-library Python with no network imports: a screenshot layout diff, a parity score, a review ranker that drops unlinked quotes, and a sweep that blocks deploy while the original's name or colors remain. The real cost is agent time; the author says a booking tool is weeks. Solo builders and small teams: a decent competitor-build checklist. Larger teams already have a product process.

The catch: "clone any app" is the headline, and the fine print walks it back to features and flows, clean-room style: no scraping behind logins, trademark checks, a lawyer before launch. Good guardrails, but they're prompt instructions, not enforcement, and the legal risk is yours. It's also one commit with five unmerged PRs, one reporting the plugin install loads none of the skills. Copy the folders.
